Digital gold currencies are issued by a number of companies, each of which provides a system that enables users to pay each other in units that hold the same value as gold bullion. These competing providers issue a type of independent currency.
Proponents claim that DGC offers a truly global and borderless world currency system which is independent of exchange rate variations and political manipulation. Gold, silver, platinum and palladium each have recognized international currency codes under ISO 4217.
Unlike fractional-reserve banking, DGCs hold 100% of clients' funds in reserve as gold, silver, and/or platinum, which can be exchanged via digital certificates. Proponents of DGC systems say that deposits are protected against inflation, devaluation and other economic risks inherent in fiat currencies. These risks include the monetary policy of countries or territories, which are said by proponents to be harmful to the value of paper currency.
can be used to buy, hold, and sell precious metals, but do not promote themselves as an "investment", as this implies an anticipated return.
Some providers do not sell DGC directly to clients. For those DGCs, e-currency must be bought and sold via a digital currency exchanger.
